DTC Description

INFOID:0000000010702945

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (The EOT sensor circuit is open or shorted.)
• Engine oil temperature sensor

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine and wait at least 5 seconds.

2.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Proceed to 

ECM-244, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010702946

1.

CHECK ENGINE OIL TEMPERATURE SENSOR POWER SUPPLY CIRCUIT-1

1.

Turn ignition switch OFF.

2.

Disconnect engine oil temperature (EOT) sensor harness connector.

3.

Turn ignition switch ON.
